please provide a walkthrough of how the book gets the answer AFN = 646,000 and why the capital intensity is differnt. Thank you!

17-1 Carlsbad Corporation's sales are expected to increase from $5 million in 2021 to $6 million in 2022 , or by 20%. Its assets totaled $3 million at the end of 2021.

What additional funds would be needed if the company's year-end 2021 assets had been $4 million? Assume that all other numbers are the same. Why is this AFN different from the one you found in Problem 17-1? Is the company's "capital intensity" the same or different? Explain.
